Demonstrators occupy a luggage area as around 100 pro-Palestinian activists stage a protest at Brussels national airport in Zaventem early April 15, 2012. Some 1,200 Palestinian supporters throughout Europe have bought plane tickets for an April 15 visit to the West Bank as part of a campaign called “Welcome to Palestine”. Organisers said the aim was to help open an international school and a museum, but Israel has denounced the activists as provocateurs and said it would deny entry to anyone who threatened public order.
